2 Claims. 1

This invention relates to a power drill support and is particularly useful as a support for an electrical drill and the like.

In the operation of electric drills, there is considerable danger when the drill point or bit passes through the object being processed and particularly at the precise instant when the drill passes through the last bit of metal. At this instant, when the metal resistance is uneven and the drill clears the metal object, there is a lateral swing involuntarily caused by the operator which very often breaks the drill bit and sometimes injures the operator.

An object of the invention is to provide means for supporting the electric drill or power tool in such a manner that when the drill passes through the last bit of metal, the drill itself remains suspended and does not swing laterally. Yet another object is to provide improved means for supporting the electric drill, etc., whereby the ball connection of the drill is releasably clamped to the support structure and in such a manner that manipulation of the drill for accurate handling and adjustment of its length and angle can be brought about. Other specific objects and advantages will appear as the specification proceeds.

The invention is illustrated, in a preferred embodiment, by the accompanying drawing, in which- Fig. l is a perspective view of support apparatus embodying my invention; Fig. 2, a. broken longitudinal sectional view, the section being taken as indicated at line 2 of Fig. 1; and Fig. 3, a perspective view of the sleeve and clamp mechanism.

In the illustration given, A designates a base support; B a standard carried thereby; and C a beam mounted upon the standard.

The base A may be of any suitable construction. In the illustration given, it consists of two channel members l and l l facing outwardly and secured together at one end by a tubular member 12. At the opposite end, the spaced members l0 and H are connected by a metal strap [3.

The standard B is mounted within the tubular support l2.

Adjustably mounted upon the standard B is the beam C which is preferably formed integrally with a collar [4 receiving the standard B and secured thereto by set screws l5.

The power tool in the illustration given is an electric drill D and it is provided at its top with a tubular connection or handle l6.

As shown best in Fig. 2, the beam C is received 2 within a bracket member ll provided at its top with a set screw Ila. The bracket I! has releasably secured to its lower side a recessed plate 18 providing an annular recess l9.

A screw extension member 20 is provided with a head 2| received within the recess l9 and rotatable therein. It is confined in position by the plate l8 secured by screws 22 to the flange of bracket ll.

Fixed to the screw member 20 is a collar 23 provided with integral laterally extending arms 24. The arms 24 may be grasped for rotating the screw member 26 for the vertical adjustment hereinafter described.

The lower threaded portion of the screw extension member 20 threadedly engages the sleeve 25. The sleeve 25 carries a fixed pin 26 at its upper end and a stud 21 at a lower point, the outer end of stud 21 being threaded. A clamping member 28 is apertured to receive the guide pin 26 and also apertured to receive the stud 21. A wing nut 29 is employed for engaging the outer threaded end of stud 2'! and for moving the clamp 28 inwardly.

The sleeve 25 is provided at its lower side with a clamping plate 30 having spaced horizontal bars 3| and 32 on its inner side. Similarly, the clamping member 28 is provided on its inner side with integral inwardly extending horizontal bars 33 and 34.

The sleeve 25 is provided near its lower side with a tube 35 which is preferably welded to the sleeve 25, and a guide bar or control bar 36 is slidably received within the tube 35.

Operation In the operation of the structure, the parts are assembled as shown best in Fig. 1, with the beam C mounted at the proper height upon standard B and the clamp 28 is released and moved laterally so as to provide an opening for the tubular connection l6 of drill D. The tubular connection I6 is inserted into the position illustrated in Fig. 2, and the clamp 28 is moved inwardly by rotating the wing nut 29. In this way, the spaced bars 3|, 32, 33 and 34 are brought into engagement with the inner portions of member l6 and thus support the handle in position, as shown best in Fig. 2. Movement of the drill is controlled by the guide bar 36 which releasably engages the tube 35. Vertical movement of the drill is effected through the rotation of the member 23 and screw 20. Lateral movement of the drill is brought about through the sliding of the bracket l1 upon the beam C.

In the operation of the drill, control of the position of the drill is readily accomplished and the drill is held upon a selected spot by use of the guide bar 36. The drill is fed downwardly by rotating the control member 23 and when the last bit of metal is cut through, the drill is completely suspended upon the beam C. No lateral movement results and there is no danger of breaking of the bit or injury to the operator.

The apparatus is simple, sturdy, and provides complete support for the power tool at all points during its operation and particularly at the critical points indicated.

While in the foregoing specifications, I have set forth certain parts of the structure in considerable detail for the purpose of illustration, it will be understood that such details may be varied widely by those skilled in the art without departing from the spirit of my invention.

I claim:

1. A support for a power tool equipped at its top with a cylindrical handle, comprising a base, a standard supported thereby, a beam carried by said standard and extending laterally therefrom, a bracket slidably mounted on said beam and equipped with a bottom flange, a plate recessed along its upper side and centrally apertured to provide a recess between it and said flange, said plate having a, central aperture therein, an extension member having a flat circular head received within said recess and provided with a depending threaded portion and with laterally-extending actuating arms, means for securing said plate to said flange, a sleeve member threadedly receiving the threaded portion of said extension member, said sleeve having a pair of horizontally inwardly-extending bars at its lower side, said sleeve having also a pair of laterally-extending pins, at least one of which is threaded, a plate apertured to receive said pins and horizontally guided thereon and having inwardly-turned spaced bars aligned with the bars of said sleeve member, and a clamp threadedly engaging the threaded pin for pressing said inwardly-extending bars about the cylindrical handle of said power tool.

2. A support for a power tool equipped at its top with a cylindrical handle, comprising a base, a standard supported thereby, a beam carried by said standard and extending laterally therefrom, a bracket slidably mounted on said beam and equipped with a bottom flange, a plate recessed along its upper side and centrally apertured to provide a recess between it and said flange, said plate having a central aperture therein, an extension member having a flat circular head received within said recess and provided with a depending threaded portion and with laterally-extending actuating arms, means for securing said plate to said flange, a sleeve member threadedly receiving the threaded portion of said extension member, said sleeve having a pair of horizontally inwardly-extending bars at its lower side, said sleeve having also a pair of laterallyextending pins, at least one of which is threaded, a plate apertured to receive said pins and horizontally guided thereon and having inwardlyturnedspaced bars aligned with the bars of said sleeve member, a clamp threadedly engaging the threaded pin for pressing said inwardly-extending bars about the cylindrical handle of said power tool, said sleeve member being provided with a tube, and a bar slidably received within said tube and adapted to be extended to engage said standard.
